Choosing the Right Size
Selecting the right outboard motor size depends on several factors, including:

Consider the size and type of your boat. Smaller boats typically require smaller motors, while larger vessels benefit from more powerful engines. Ensure the motor’s weight and size are suitable for your boat’s transom.
2. Intended Use

Ensure that your chosen motor can handle the weight of your boat, passengers, and gear. Overloading a motor can lead to performance issues and safety concerns.

Larger motors tend to consume more fuel, so consider your budget for fuel costs. Yamaha motors are known for their fuel efficiency, but it’s still essential to choose a size that matches your usage patterns.
